To all whom t may concern:

Be it known that l, Roanne? EDw'IN REAR- nen, a subject of the King of Great Britain, residing in the city ofvl/Vashington, District of Columbia, United tates of America, havekinvented ar new and useful Improvement in Shooting-Practice Dummy Guns, oi which the YSollowing is a specification.

This invention is a development of the subject oi my United States Patent LNumber l,it2,i20, for new and useful improvements in dummy practice rifles, and relates to further improvements in imitation or dummy rifles affording training in accurate shooting. The object of this invention is to enlarge the iield of usefulness of such devices t'or cadet, school and home training, by simplifying construction, lessening cost of manufacture, while maintaining or increasing operating accuracy, and providing simple and safe new means of using dummy cartridges with shooting prac tice dummy guns to add interest and instructiveness by Simulation of loading and ejection actions.

1With these objects in view the invention consists in the arrangement, construction and combinationfo'f parts hereinafter described and yparticularly pointed out in the claims, it being understood that I do not limit myself to the details oit construction ot the several parts.

"in the drawings like numbers refer to similar parts. l

`The gun body is designated bythe numeral l. incorporated in the gunf body in the simple cartridgel'ess form oli' my 'shooting practice dummy gun 'shown in AFigure l, are: a target hitting barreljcore 'rod 2; a hammer plunger rod 3; a hammerplunger arresting and releasing trigger 4c with a nose 2l adapted to interpose spacev between the hammer,y plunger face and the butt of the barrel core rod when operating to arrest the hammer plunger; aftrigger pivot 4B; a oresight-'muzzle-band piece 5; a rearsight-breechstop piece 6, through an aperture in which the hammer plunger rod has limited rearward" sliding movement, shown as a separate,partv for convenience of manufacturejbut kotherwise integral with the gunbody; a orwar'dbar rel core rod stop bushing 7, shownas pinned by pin 7 in separatepart for convenience of manufacture but otherwise integral with the gun body; a barrel core rod butt piece 8 and hammer plunger' rod head piece 9, respectively shown as separate parts for convenience ot manufacture but otherwise integral with the parts to which they are attached; a barrel core rod retracting spring 10; a hammer plunger rrod advancing spring 11; a hammer plunger rod stop-knob 12; a trigger spring 13; a foresight-muz zleband attaching` screw 14; a rear-sightbreechstop piece attaching screw 15. The barrel core rod 2 is shown inplligures 1, 2, v3 and (iwith a dat, or hammer, tip 33, which may be replaced by other forms of tip, particularly 'such as shown in Figures 7, 8 and 9.

ln the simple dummy cartridge using modification o my shooting practice dummy gun shown in Figures 2 and Ll, the part designated by numeral 6, namely the butt enlargement of the barrel core rod, 2, is constructed with a trough 16 in it, formed vasa rearwardly extending semi-cylindrical pan with a ridge terminal butt 20 and haying lying in the bottom of the said trough 16 a vtiltable` longitudinal plate 17 loosely pivoted at the butt end having thereat a tilting tip 18 projecting downwardly beg low the trough bottom into the path oiQ a tripper 19 and adapted to engage same and tilt the trough plate 1? when the lairrel core rod 2 is retiring. The tripper 19 is pirotally mounted 19A in such manner as to not impede forward movement oit the barrel corel rod 2. An aperture 16A in the gun body 1 above normal position or the trough 16 permits a dummy artridge 22 to be insertedin the said trough. A stud 25 on the under side of the troughed core rod butt 8 engages a longitudinal groove 25A in the barrel bore of the gun body 1, thus maintaining the cartridge trough 16 always iao- :ing towards the cartridge loading aperture side of the `barrel bore of the gun body. rlhe trigger 4 in this modification or my C@rooting practice drill gun may be con- Quoted With an approximately squared nose l u'hich thus acts to arrest the hammer plunger 9 When retreated, stops retreat oli ,-arrel core rod butt against the hammer plunger 9, When gun is fcoclred and may alsobe made instrumental in the ejection through the loading aperture 16A ot the dummy cartridge 22 by the tilting plate 1T, by abutting, as the barrel core rod 2 retreats after tiring action, the lower edge of the dummy cartridge head, which projects rearwardly beyond the trough 16, the ridge ,20 in the butt of which engages the caun nelured neck 22A in the cartridge 22.

The operation of the forms of my shooting practice dummy gun shor'vn in Figures 1 and 2 is performed byk grasping vthe stoplznob 12 and pulling the hammer plunger rod 3 straight bach, compressing the hammer plunger rod sjiiring 11 until the hammer plunger 9 is engaged by the elevated nose 2l of the [trigger el, actuated by the trigger spring 13, the barrel core rod 2, actuated by its reti-acting spring 19, r'olloiving the hammer plunger 9 back until it abuts the orward edge or the trigger nose 21. Aim is then talren at a target, over the Vforesight in part 5 through the pecpsight in part 6, and the trigger -l pressed, releasing the, hammer plunger 9 against the butt 8 of the barrel core rod (which may be solid ror troughed as stated) with the torce of the liring spr/ing 11, thus driving the barrel core rod 2 rorWard through the barrel and the stop bushing 7 until the compression of the retracting spring 1U impels its return to normal position in the gun body l.

lit the iform of my shooting practice dummy gun shown in Figure be used and it be desired to simulate the loading action in connection with the aiming practice, a dummy cartridge 22 is inserted through the cartridge loading aperture 16A in the gun body 1 into the trough 16 oit the barrel core rod butt 8 before cooking, aiming and firing action. ldhen the gun is fired the dun'imy cartridge rides forward in and with the trough 16 or the barrel core rod butt S in which it Was loaded and is automatically ejected by the retraction ot the barrel oore rod 2, by the gravity intercepted tripper 19 engaging the downwardly projecting tip 18 of the tilting plate 1'? in the cartridge trough 16 as the trough mouth comes opposite to the loading and ejecting aperture 16A in the gun body 1. A single dummy cartridge may be loaded in and ejected continuously, or a number of dummy cartridges used in successive loading from a cartridge belt, or pouch, as giving more realistic simulation of cartridge use.

ln the more military form of my shooting practice dummy gun shown in Figure 3, the foresight-muzzleband 5 is of approx imately military rifle design and the rearsight-breechstop 6 is formed with a ham mer-plunger-sleeve-looking recess 24, and shoulder 26 in its base. The barrel core rod stop bushing is elongated to protrude troni the muzzle end or the gun body in simulation of a real rifle barrel: the hainmer plunger 9 is formed as cartridge trough 16, differing from the trough construction used in Figure 2 in having both ends of the trough or full height, and the tilting plate 17 loosely secured in the bottom of same by the downwardly projecting tilting tip 18 being bent into hoolr form. The tilting tip in this modilication rrides in a recess 4^ in the trigger 4 Whioh'extends rearwardly from its nose 21 and the tip engages at the limit of its rearward travel the rear shoulder 241 of said trigger recess 4A, thereby operating the tilting plate 17 in the bottom of the trough 16 to ejectv a dummy cartridge, ot any readily insertable size, through cartridge loadingl and ejecting aperture 16A in the hammer plunger sleeve 27 and a registering opening in the gun body 1, when the hammer plunger 9 encased in its sleeve 27 is retracted a trifle rearward of the point at which the trigger nose 21 engages the hammer plunger 9 against advance niovement. In this modification of my shooting practice dummy gun the hammer plunger 9 is mounted in an encasing sleeve 27 which has a manipulating arm 30 and a locking lug 28 at the rear end thereot disposed to engage by limited rotation the recess 29 and its shoulder 26 in the base rear side ot the rear-sight-breechstop 6.

ln Figure 3 the hammer plunger sleeve 27 is shown unlocked, in retracting position, with its manipulating arm raised and its cartridge loading and ejection aperture, or slot, 27A, registering with the mouth of the cartridge trough 16 in the hammer plunger 9. The lower side of the hammer plunger sleeve 27 has in it a longitudinal slot 27B of sufficient width to permit of the necessary rotation to lock the sleeve lug 28 in the rearsight breechstop recess 29, rotate the sleeve body to cover the cartridge trough 16, and also allow longitudinal travel of the tilting plate tip 18 and the trough uprighting stud 25 on the under side of the cartridge trough.

rlhe trigger' 4 in this moditication is elongated forwardly on account of the increased length ot the hammer plunger 9; has a recess 4A between its nose 21 and a rearward shoulder' 24 adjoining its pivot 4B; and is `upwardly raised by a modi# tied trigger spring 13, consisting of a flat spring mounted to bear against the under side of the forward elongationk of the nose arm and the upper surface of a trigger guard 31, both the spring 18 and the guard 31 being held in position by gun body band 82 and its screw 82A.

This approximately military modification of my shooting practice dummygun, or rifle, shown in Figure 3 is operated in practically the same manner as the modification shown in Figure 2, with the exception that the hammer plunger 9 encased in its sleeve 27 is rendered rearwardly movable through the fixed rearsight-breech-stop 6 by upwardly rotating the sleeve 27 out of lug 28 engagement with recess 29 thereof, by means of its manipulating arm 30, which action also brings the cartridge loading and ejection aperture 27A into registration with the mouth of the cartridge trough 16 and into alignment with gun body aperture 16A; then drawing back freely the sleeve 27 encased hammer plunger 9` until the nose 21 of trigger 4 rises in front of the hammer plunger 9 to intercept its ree turn. A dummy cartridge 22 may then, if

cartridge loading simulation is desired, be inserted in the trough 16 and the sleeve 27, by means of manipulating arm 80, advanced, against the hammer plunger rod spring 11 upon the arrested hammer plunger 9 until the lug 28 on the but-t oic sleeve 27 can be locked with -the rear-sight-breechstop 6 again by rotation otl sleeve lug 28 into' recess 29 in the rearsight-breachstop 6.

There are several advantages in the construction adopted in this modification of my shooting practice dummy gun, namely, the better simulation of real military riiie loading action and the possible use of dummy cartridges of any weight., because ot the cartridge trough being in the plunger hammer 9, to which additional weight is an advantage, whereas only light weight dummy cartridges may be used when the cartridge trough 16 is in the butt 8 of the barrel core rod 2, as shown in the modification of my shooting practice dummy gun illustrated in Figure 2.

Various targetting tips may be used upon the barrel core rod 2 of my shooting practice dummy gun, according to the nature of the target. The novel flat faced head, or hammer, tip, 33, shown on the barrel core rod in Figures 1, 2, 8 and 6 is adapted for use against a target which indicates hits by sound or action caused by impact. The ink pad and pencil marking tips respectively illustrated in Figures 7 and 8, a disk-like ink pad 34 being pivotally mounted at 34A to normally press against the tip of barrel core rod 2 by the head of the receded rod riding on a forked, right angular bow spring arm of the ink pad 84, and 36 being` a pencil vlead held in a tubular holder 87 mounted on the tip of barrel core rod 2, are types of rod tip shown and described in my hereinbefore mentioned original United States patent application on dummy practice riiies, which may be used in combination with myV herein described improvements in shooting practice dummy rifles. I have devised a novel, improved form ot ink marking projectile rod tip shown in Figure 9. It consistsof an ink capsule or vial 38, of rubber or other preferably resilient material, having a perforated marking point 46 connected by capillary duct or ducts 47 with an interiorcavity filled with ink, the whole being resiliently mounted on the muzzle end of the projectable barrel core rod 2. The perforated target marking point 46 on the ink'capsule 38 protrudes as from the center of a thick rimmed saucer in the target contacting face of the ink capsule 88, the surrounding depression 48 preventing smear marking of the target by ink spreading from the marking point 46, and the thick surrounding saucer rino7 or ridge 48, protecting the point 46 by offering resistance to point crushing impact on the Cil lll)

target; these features ensure clean printing` pressure oi? the fountain ink marking point- 46 on the target. The ink feeding capillary duct, or ducts, 47, preferably in plurality as shown in Figure 9, lead trom the perforated marking point 46 to the ink cavity 50 axially of t-he chamber and diagonally to its walls, so that, no matter what side ot the cavity 46 is horizontally undermost in targetting operation, the ink will always, down to its lowest level, be in duct connection with the marking point 46. The ink cavity, or chamber, 50 or the ink capsule Iti as shown in Figure 9 is plugged at its base with a cork 44 after being filled with ink, but might be lilled by the manufacturer and sealed. The ink capsule 3S as illustrated in Figure 9 is inserted in a holding cup 39 with a flanged base 59A and a stem 4l that is seated in a well 42 in the head of the barrel core rod 2 of my shooting practice dummy gun. A retaining and guiding ferrule, or cylinder, 40, with an inward flange 45 at its forward end against which the base flange 39A ot the holder cup 39 is normally advanced by a holder cup stem compression spring 43, ensleeves the holder cup 39 and att-aches it to the head of the barrel core rod 2.

My improved shooting practice dummy gun as illustrated and described herein is designed to be constructed mainly of wood, with metal or other substance used only where advisable or essential, to give weight, wearing quality, spring elect, compactness, etc.

I claim l. In a new article of manufacture a shooting practice dummy drill gun comprising a gun body part having a cartridge insertion aperture, a spring retracted, longitudinally movable barrel core part, a spring hammer plunger part tor giving i'orward impetus to said barrel core part, a cartridge trough in the hammer plunger part, and spring trigger means for arresting and releasing said spring hammer plunger part.
